I. SYSTEM DESCRIPTION
The Viking ESFR Pre-Primed Single Interlock Preaction Cold Storage System is a fixed fire protection
system designed for installation in refrigerated, cold storage and unheated warehouse applications
with rack storage of Class II commodity on wood pallets. This system effectively prevents frost plugs
associated with systems that supervise the piping network with air. The single interlock preaction sys-
tem piping network is supervised with a propylene glycol solution. When using this system for single-,
double- and multiple-row rack storage, Viking K25.2 ESFR sprinklers are used at the ceiling only and
no in-rack sprinklers are required.
1. System Considerations
All materials installed on the system shall be compatible with propylene glycol solution.
Where the minimum temperature in the area being protected is 8 °F (-13.3 °C) or above,
Firefighter Eliminator C 35% percent by volume propylene glycol factory premixed solution
must be used.
Where the minimum temperature in the area is between 8 °F (-13.3 °C) and -21 °F (-29.4 °C),
firefighter Eliminator F 50% percent by volume propylene glycol factory premixed solution
must be used.
The minimum ambient temperature where the system can be used is -21 °F (-29.4 °C). This
is not an average temperature; it is the lowest temperature within the area.
The system piping configuration shall be designed in a tree configuration only. The
mains and branch lines should not be looped together. Grid systems are NOT allowed. The
piping system shall be pitched to drain completely. The branch lines shall be pitched at ¼”
per 10 ft (4 mm/m) run of pipe and the mains shall be pitched ½” per 10 ft (4 mm/m) run of
pipe.
2. System Makeup
Each Viking ESFR Pre-Primed Single Interlock Preaction Cold Storage System requires the fol-
lowing components for proper operation:
Water Supply Control Valve
Deluge Valve with Conventional Deluge Valve Trim
Electric Release Trim with Solenoid Valve
Primary Easy Riser®Check Valve with Cold Storage Trim including Automatic Pressure

This system shall be designed by qualified fire protection professionals in conjunction with the
requirements listed in this technical data, NFPA 13, and those of the authority having jurisdiction.
The system designer must read and apply all of the following design requirements.
II. SYSTEM DESIGN
1. Hydraulic Calculations
Two hydraulic calculations are required for the system:
The first calculation shall be with the 12 Viking VK510 K25.2 ESFR’s assuming they are flowing
water. This calculation shall include 4 sprinklers on the 3 most hydraulically remote branch lines
discharging at the minimum design pressure for the system. This calculation shall use the Hazen
Williams formula. See examples in Figures 3 & 4.
The second calculation shall include 6 Viking VK510 K25.2 ESFR’s flowing propylene glycol
solution. The calculation shall include 4 sprinklers on the most hydraulically remote branch line
and 2 sprinklers on the second most hydraulically remote branch line discharging at the minimum
design pressure required for the system. This calculation shall use the Darcy-Weisbach formula.
See examples in Figures 6-8.
Full-scale fire testing has demonstrated that the propylene glycol solution will be expelled from
the system by the time 6 sprinklers are operating in a fire condition. The 6-head sprinkler calcula-
tion using the Darcy-Weisbach formula is used to ensure that the piping has been sized properly
and the water supply is adequate for the more viscous liquid. Because the propylene glycol will
have a dramatically different viscosity at the colder temperature expected in this application, fric-
tion loss through the piping network will be significantly higher than water.
When conducting hydraulic calculations, a good rule of thumb is to increase pipe size when
friction loss has reached .3 PSI per foot of pipe. By setting up the spreadsheet described in
Appendix B, a quick estimation of the difference in friction loss will assist in determining if the
desired pipe size will be adequate. The final pipe sizes will need to be confirmed through the
actual hydraulic calculations.

Typically, when a partial branch line is required in the hydraulic calculations, the sprinklers closer to
the cross main will be used, as shown above. The calculation of the closer sprinklers will result in less
friction loss and a smaller pressure demand on the branch line. At the cross main, a K factor for the
branch lines will need to be determined. The lower pressure requirement will result in a larger K fac-
tor and thus require more water on the partial branch line, typically making the closer sprinklers more
demanding.

Darcy-Weisbach Method for Calculating Friction in Piping:
Most hydraulic calculation software used in the sprinkler industry today has the option for conducting
the piping friction loss calculations with the Darcy-Weisbach method. The reason for conducting the
additional 6 sprinkler head calculation is to verify that the available water supply pressure is adequate
for the initial discharge of propylene glycol solution. The example calculations provided in Figures 6-
8 illustrate the difference in results that can occur when calculating for the more viscous propylene
glycol solution versus the standard Hazen-Williams calculation for water illustrated in Figures 3-4.
For those not familiar with the Darcy-Weisbach method below is the basic procedure that is used to
conduct the calculation. This is intended only to provide the designer with an understanding of the
concepts of the method. It is not practical that the calculation be done by hand as this would be much
too time consuming and subject to potential errors.
The Darcy-Weisbach Formula as found in most text is written as: h= (f) (l) (v)2/ (d) (2) (g)
h=friction loss (ft of head)
f=friction factor (from Moody Diagram-Figure 10)
l=length of pipe (ft)
v=velocity (ft/sec)
d=diameter of pipe (ft)
g=gravitational constant (32.2 ft/sec2)
This formula can be rearranged and simplified to:
When the calculated Reynolds Number (Re) is >2000 =0.000216 fLρQ2/d5=Friction Loss (psi)
When the calculated Reynolds Number (Re) is <2000 =0.000273 μLQ/d4=Friction Loss (psi)
Where:
Re=50.6Qρ/dμ
Q=flow (gpm)
ρ=density (lbs/ft3)
d=internal pipe diameter (in)
D=internal pipe diameter (ft)
L=pipe length (ft)
μ=dynamic viscosity (cps)
ε= .00033 for steel pipe
f=friction factor, If Re > 2000, use Moody Diagram (Figure 10). If Re < 2000, f = 64/Re.
Procedure:
1. Calculate Reynolds Number (Re) = 50.6Qρ/dμ
2. Calculate relative roughness of pipe = ε/D
ε= .00033 (ft)
D=internal pipe diameter (ft)
3. Use Moody Diagram (Figure 10) to find “f” if Re > 2000. If Re < 2000, f = 64/Re.
4. Use fiction loss in hydraulic calculation.

Example:
Assume 100 ft² spacing, 10 ft between the sprinklers and 10 ft between the branch lines.
Schedule 10 Pipe.
3” Pipe = 300’ x .433 = 129.9 gal.
4” Pipe = 20’ x .740 = 14.8 gal.
6” Pipe = 74’ x 1.649 = 120.0 gal.
Total Volume = 247 gal.
* Note: Based on the installation history of this system, systems near 25,000 ft2 in area, with long runs on feed main, typically
begin to approach the 1,100 gallon restriction, or begin to demand excessive pressures in the Darcy-Weisbach calculation.
This history can be used as an estimating tool, however, the actual system volume must be calculated.
•
•
The system design area (12 sprinklers: 4 on each of the 3 hydraulically most remote branch lines)
and bulk main to the primary Easy Riser®Check Valve (lines in bold) at the base of the riser is
limited to a total volume of 1,100 gallons.* Additional mains and sprinkler lines attached to the
sprinkler system, but not in the direct path to the base of the riser, do not need to be considered
in the volume restriction.
The actual volume of propylene glycol solution for the sprinkler system is determined by adding
all the sprinkler piping together. Additional propylene glycol is added to this total for the CS-1
Tank and supply lines to the riser.

3. Typical Storage Arrangements
Definitions:
Class II Commodity - A Class II commodity shall be defined as a noncombustible product that
is in slatted wooden crates, solid wood boxes, multiple layered corrugated cartons or equivalent
combustible packaging material with or without pallets.
Longitudinal Flue Space - The space between the rows of storage perpendicular to the direc-
tion of loading.
Transverse Flue Space - The distance between rows of storage parallel to the direction of load-
ing.
L = Longitudinal Flue Space
T = Transverse Flue Space
Racks that have no longitudinal flue space
and that have width up to 6 ft, and aisles at
leas 3½ ft from any other storage.
Two single row racks placed back to back
having a combined width up to 12 ft with
aisles at least 3½ ft on each side.

Notes:
The system is acceptable for use with Class I and Class II commodities only.
For use with a maximum 50% by volume propylene glycol and water antifreeze solution with
a maximum ceiling height of 40 ft (12.2 m) and a maximum Class II commodity height of 35 ft
(10.7 m) with a maximum deflector distance below the ceiling of 18” (457 mm). The minimum
starting pressure is 40 PSI (2.76 Bar).
For use with a maximum 50% by volume propylene glycol and water antifreeze solution with
a maximum ceiling height of 45ft-3 in (13.8 m) and a maximum Class II commodity height
of 40 ft (12.2 m) with a maximum deflector distance below the ceiling of 14” (356 mm). The
minimum starting pressure is 60 PSI (4.14 Bar).
The VK510 ESFR’s shall be ordinary temperature 165 °F (74 °C) except where required to
be intermediate temperature 205 °F (96 °C) due to close proximity to heating sources as
described in NFPA 13.
The system shall be designed so that the maximum operating pressure does not exceed 175
PSI (12 Bar) at the ESFR sprinklers.
Only wood pallets are acceptable.
